Fix dump config ignore tables format

"Ignore table format is db.table " is not right, and fix the problem with ","
and please see canal/canal.go:162-166    "seps := strings.Split(ignoreTable, ",")"

canal/canal.go:162-166行

        for _, ignoreTable := range c.cfg.Dump.IgnoreTables {
		if seps := strings.Split(ignoreTable, ","); len(seps) == 2 {
			c.dumper.AddIgnoreTables(seps[0], seps[1])
		}
	}

忽略的表(ignoreTable),用逗号分隔 DB和table,这里好奇怪,不知道为什么,但是
canal/.go:25-26行

       // Ignore table format is db.table
	IgnoreTables []string `toml:"ignore_tables"`

要求用” . “来间隔。

这里原先应该就是正确的吧?
database1.table1,database2.table2,逗号是用来分割不同的表,句点是用sql语法将database和table做分割吧?

		c.dumper.AddIgnoreTables(seps[0], seps[1])
	}
}

seps[0]是DB,seps[1]是table
根据 strings.Split(ignoreTable, ",")源代码来看,他们是通过 “,”来链接的

而注释
// Ignore table format is db.table
IgnoreTables []string toml:"ignore_tables"

要求用“.”来连接,所以自相矛盾啊
